High-Resolution Finite Volume Methods for Dusty Gas Jets and Plumes

Numerical Analysis of Opposed Rows of Coolant Jets Injected into a Heated Crossflow

The mixing characteristics of coolant air jets with the hot gas exiting the gas turbine combustor’s primary zone is of major importance to the combustor exit temperature profile. In the present work, a three dimensional numerical simulation on the basis of the finite volume method was developed. The aim was to investigate the penetration and mixing characteristics of directly opposed rows of co...

A finite-difference analysis of turbulent, axisymmetric, buoyant jets and plumes

Three-dimensional visualization of multi-phase (oil/gas/hydrate) plumes

Abstract Visualization of multi-phase jets and plumes is a relatively new subject. Discussions on how to visualize them have not been seen elsewhere. Multi-phase jets and plumes (e.g. a plume from a deep water blowout that consist of a mixture of oil, gas, and gas hydrates) undergo phase changes during the transport of fluids up the water column. Effectively visualizing all the pertinent jet or...

Numerical Simulation of the Hydrodynamics of a Two-Dimensional Gas—Solid Fluidized Bed by New Finite Volume Based Finite Element Method

n this work, computational fluid dynamics of the flow behavior in a cold flow of fluidized bed is studied. An improved finite volume based finite element method has been introduced to solve the two-phase gas/solid flow hydrodynamic equations. This method uses a collocated grid, where all variables are located at the nodal points. The fluid dynamic model for gas/solid two-phase flow is based on ...

Runge-Kutta discontinuous Galerkin methods for compressible two-medium flow simulations: One-dimensional case

The Runge–Kutta discontinuous Galerkin (RKDG) method for solving hyperbolic conservation laws is a high order finite element method, which utilizes the useful features from high resolution finite volume schemes, such as the exact or approximate Riemann solvers, TVD Runge–Kutta time discretizations, and limiters. In this paper, we investigate using the RKDG finite element method for compressible...
